The problem with such apps is that they don’t support all the assorted data types in Health.

With iOS 11, those worries are a thing of the past as more Apple apps are now able to securely synchronize their data across devices via iCloud, including Messages, Siri and Health.

This removes a significant pain point for anyone looking to retain their Health data as they set up their devices from scratch. Or, maybe you have two iPhones and would like your Health database available and kept in perfect sync on both?

With just a few taps, you can.

With this feature, your complete Health database becomes available after you sign in with your Apple ID on the new phone and flip a switch in Settings. Health syncing is off by default due to the sensitive nature of private medical information.

How to sync Health data across multiple iPhones

1) Launch the Settings app on your device.

2) Tap your profile image with your Apple ID at the top of the screen.
